How do I drop the fuel tank on a 1993 Nissan Altima?
My 1993 Nissan Altima was leaking Gas from where the fuel lines come off the tank (out of view) when he turned on the ignition. the car would run fine but still leaked gas (a large amount). I tried to drop the tank but it is held up by the exhaust system as far as I can tell. Since that would cause more problems, I was hoping to get some suggestions.

If you mean the fuel line,start the engine, then remove the fuel pump relay , when not enough fuel pressure to run the engine, it will die and line will be depressurized. The tank itself only has minimal pressure which is vented. Removing the filler (gas) cap will relieve any excess pressure in the tank...Mike
Fuel pump is a complete assembly set inside the fuel tank. You'll need to drop the tank, (you might want to remove the gas FIRST) unplug the wiring, disconnect battery, all fuel, return, and vapor lines, etc. You should get someone experienced if this is your first time. It's a big job.
MOST fuel filters are either prior to the entrance to the fuel pump on the fuel line, OR under the vehicle attached to the framework, follow the fuel line from the top of the gas tank until you locate the filter receptacle...
it could be a bad belt or signs that the fuel pump is getting weak put some STP gas treatment in the gas tank make sure you have at least a half a tank of gas before you do this ask yourself when was the last time you changed the fuel filter
Your fuel filter could be stopped up, injectors could be stopped up or there may even be a fuse for fuel. May also be your fuel pump, which is generally in the fuel tank. If you turn your ignition on, don't crank it, see if you can hear a whining noise coming from the gas tank neck(where you put the gas in). Hopefully that is NOT your problem.
